Title: Improvements in rotary folding mechanism for printing machines
IPC: B41F33/00
Filed: 1936-08-26
Abstract: 482,578. Photo - electric control of paper-folding mechanism. HOE & CO., Ltd., R. (Horton, A. J.) Aug. 26, 1936, No. 23451. [Class 40 (iii)] [Also in Group XVI] Relates to rotary folding mechanism for printing-machines having means for protection against damage due to chokes, the machines being of the kind comprising a cylinder to which sheets are normally fed at regular intervals and from which the sheets are regularly forwarded to folding rollers. According to the invention, the initiation of a choke is detected by two co-operating control elements, one of which operates at regular periods during which a sheet is normally absent from (or present at) a predetermined point, and the other of which responds to the presence (or absence) of a sheet at the said point during such periods ; when response of the second control element occurs, means are rendered active to discontinue the supply of sheets to the folding- mechanism, e.g. a switch in the circuit of the driving motor is opened, or a device operates to sever the web fed to the cylinder. A lightsensitive device is used as one of the control elements in the apparatus shown which illustrates the use of two independent control arrangements, one of which operates by detecting the presence at an improper time of a sheet 15 upon the portion 21 of the folding cylinder 12, and the other of which operates by detecting the absence of a sheet when it should be below the rollers 17, 18 at a point 36. A paper web 11 fed to the cylinder 12 is severed at 14 into sheets, each of which is carried by the cylinder into position to be directed by a blade 16 between the folding-rollers 17, 18. A photoelectric cell 30 is arranged to respond to light from a lamp 31 reflected by paper when present at the point 21 but not to respond to light reflected by the surface of the cylinder. A switch 35 in the circuit of the lamp is closed at regular periods during which when the machine is working normally there should be no paper sheet at 21. If, however, paper is present there during such a period, the cell 30 responds to the reflected light and causes a solenoid 26 to be energized. This may effect the breaking at contacts 23 of the circuit of the driving-motor, and/or by closing contacts 25 may cause a knife 24 to cut the web. In the other control-device, a cell 30<1> responds to light reflected from a mirror 37 (or, with a different arrangement of the lamp 31<1>, responds to light directly transmitted to the cell) but not to light reflected from the paper. The response occurs in this case, and stops the supply of paper to the cylinder, if a sheet is absent from 36 during any period when the lamp 31<1> is energized by closure of the switch 35<1>. The arrangements may be modified so as to operate in the reverse manner, i.e. by detecting the abnormal absence of a sheet from the point 21 or the presence of a sheet at 36 at an improper time.

Title: Method of making silica gel
IPC: C01B33/154
Filed: 1951-10-15
Abstract: Silica gel is prepared by mixing acid and sodium silicate solutions to form a hydrosol and subjecting the hydrosol in shallow layers not exceeding 1/2 -inch deep to preliminary heating to form a hydrogel and to raise the temperature of the hydrogel to 190-200 DEG F while evaporating an amount of water equivalent to from 25-50 per cent of the original hydrosol weight. The hydrogel is cut into small pieces, e.g. 1/2 -inch cube, and the pieces are partially washed with water at 150 DEG F until 25-55 per cent of the sodium salt has been removed from the gel and then partially dried at 300-350 DEG F until the moisture content is 50-55 per cent of the partially dried weight. The gel pieces are then thoroughly washed with water at 175 DEG F with several changes to remove remaining salt and finally dried to a moisture content of 6 per cent.  The preliminary heating may be effected by circulating air saturated with moisture at 250-350 DEG F for 30 minutes to 1 1/2 hours.  The physical properties of the gel are described.

Title: Improvements in determining the composition of gases
IPC: G01N7/06
Filed: 1919-10-01
Abstract: 166,266. Williams, L. D., and Williams, A. Oct. 1, 1919. Gas analysis.-Apparatus for the estimation of gas mixtures by measuring the alteration of the pressure or volume resulting from combustion or absorption of one of the constituents is adapted to work with samples under a pressure of several atmospheres by the provision of a pump and a pressure gauge. The applications include the estimation of methane in air; of hydrogen and petrol in the atmospheres of airship sheds, submarines and oil tanlsers ; and of carbon dioxide in flue gases. In one form of apparatus, Fig. 1, the gas to be analyzed, under a pressure of several atmospheres as indicated by the gauge J, is forced by a pump A simultaneously into a pressure chamber B, a combustion chamber C and a compensating chamber D. The chambers C, D are provided with diaphragms F, E and an interconnecting rod G which operates a pointer H to indicate the alteration in pressure; the combustion chamber C contains a platinum wire M, and chamber D, a gold-plated platinum wire N. On closing an electric circuit, combustion takes place in the chamber C but not in chamber D, which merely serves to compensate for the. increase in pressure due to local heating of the gas and may be dispensed with. Another form of apparatus, Fig. 4, comprises a metal chamber a containing a catalytic heater b, a diaphragm d and a superimposed chamber e, into which fits a fine-bore glass tube g containing coloured water, from which the fall in pressure can be directly read off. The, two chambers are made of differentially expanding material in order to compensate for change in temperature. In a further form of apparatus, Fig. 5, the gas under pressure is forced into two chambers l, p, one of which l contains the catalytic heater m. The difference in volume caused by combustion is measured by the movement of the diaphragm q which separates the chambers as indicated by the number of turns of the calibrated screw t required to maintain an electric circuit. In each case the apparatus may be adapted for absorption instead of combustion of the constituent to be estimated, and the metal parts are massive or water-cooled to permit of rapid relstoration of normal temperature.

Abstract: 1,268,136. Multiplex pulse code signalling; colour television. NIPPON HOSO KYOKAI. 20 May, 1970 [22 May, 1969], No. 24320/70. Headings H4F and H4L. A system for multiplexing at least one information signal, e.g. a speech signal, with a colour television signal, comprises means for sampling the information signal by pulses having a repetition frequency which is an integral multiple of the horizontal scanning frequency and converting the signal samples into a pulse coded signal in which the bit repetition frequency and phase is the same as the frequency and phase of the reference colour sub-carrier, and means for transmitting the pulse coded signal during the period of the horizontal blanking signal in the period which would be occupied by a colour burst signal in a conventional system. As shown in Fig. 4, a speech signal is sampled at 1 by pulses having a repetition frequency equal to twice the line scanning frequency, converted to digital form at 2 and stored in a register 3. A binary or ternary code may be used, different digits being represented by pulses of different amplitude or, polarity to facilitate the reconstitution of the colour reference subcarrier of correct frequency and phase at the receiver. Alternatively, one or two auxiliary pulses may be provided at the start of a coded sample to provide the colour burst information. The signals stored in the register 3 are read out during the period of the horizontal blanking signal, two successive coded samples being transmitted during each of said periods and modified as required at 4 to transmit the colour burst information. Devices 1 to 4 are controlled by timing pulses from circuit 7 derived from the horizontal driving signal and the colour subcarrier. The colour burst signal is removed from the normal television signal at 8, a synchronizing signal is added at 9 and the resulting signal is combined at 6 with the output of converter 4. An additional speech channel 11, 2<SP>1</SP>, 3<SP>1</SP> may be incorporated. The co-operating receiver, Fig. 6 (not shown), is provided with means for gating out the digital signal to reconstitute the colour subcarrier under the control of pulses derived from the sync. signal, decoding the digital signal, supplying it to a register and reading it out at the correct timing.
